Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00356 | $0.00356 |
| Opus 5.5 | $0.00142 | $0.00142 |
| Sonnet 5.5 | $0.00071 | $0.00071 |
| Haiku 4.5 | $0.00036 | $0.00036 |
Grade A, and why
whatdotheyknow-mcp CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
CLAUDE.md
This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
Project
An MCP server exposing WhatDoTheyKnow FOI request data to Claude and other MCP clients. Built with FastMCP on Python 3.13+.
Commands
This project uses uv for dependency management.
# Install dependencies
uv sync
# Run the server (listens on http://127.0.0.1:9000)
uv run server.py
# Type checking
uv run mypy server.py
# Add a dependency
uv add <package>
Architecture
All logic lives in server.py. main.py is an unused stub.
WDTKClient — thin httpx.AsyncClient wrapper around https://www.whatdotheyknow.com. Write operations require WDTK_API_KEY env var and POST via multipart/form-data.
Resources (wdtk://...) — read-only data mapped to WhatDoTheyKnow REST endpoints (authorities, requests, users, feeds, CSV). Exposed as tools via ResourcesAsTools transform.
Tools — build_request_url and search_request_events are public. create_request_record and update_request_state are tagged "write" and can be disabled at startup.
Prompt — draft_foi_request generates a system prompt guiding narrow, specific FOI request drafting.
Write API toggle — uncomment mcp.disable(tags={"write"}) in server.py to run in read-only mode.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
